Intake system for an internal combustion engine

The air intake system, for an internal combustion motor, has an air pipe (16) which is secured at one end by a flange at a motor component, e.g. the throttle flap housing (10). The flange has at least one opening, to be engaged by the fasteners to hold the air pipe securely and in a release mounting. The air pipe is a common junction pipe for two air pipes (12,14) served by air filters (2,4) and charging air coolers (6,8).
